Q: What makes the Okaya OPTT29066 the flagship in the inverter battery range?

The OPTT29066 (PROPower+) is Okaya's highest-warranty inverter battery at 66 months (42M flat + 24M pro-rata) -- the longest in the entire XBD+ lineup -- with 260Ah capacity and the best CBH values among all models tested at 100W to 400W loads. It is positioned as Okaya's best-in-class upgrade over the traditional 250Ah battery. Price: Rs 29,500.

Q: How long does the Okaya OPTT29066 (260Ah) run at different load levels?

Per Okaya's CBH declaration, verified by NABL-accredited labs under UMHD conditions: at 100W load it runs 32 hours 40 minutes, at 200W load 15 hours 5 minutes, at 300W load 9 hours 15 minutes, and at 400W load 6 hours 15 minutes. These are the highest CBH values in Okaya's standard residential inverter battery range.
